Abstract:
A numerical model for the analysis of uncertainty propagation in flow through unsaturated soils is developed. This model is based on the first -order Taylor series expansion of the discretized Richards' equation, for one -dimensional flow. Soil hydrologic properties, the saturated hydraulic conductivity and the pore size distribution, are assumed to be stochastic processes in space. The surface boundary conditions are considered to be deterministic variable in time or stochastic time series. The purpose of this model is to examine the effect of uncertainty in boundary conditions and heterogeneity on the pressure head and flux variance profiles at various times.
